The AMD R9 390X is a rebadged power hungry (350W+) 290X. The 390X has a slightly increased GPU clock speed, a significantly increased memory speed and a higher minimum VRAM of 8GB but it shares the same core GPU hardware. Looking at the overclocked performance differences between the older 290X and the 390X shows that the two cards are approximately the same, which comes as no surprise considering that the 390X is actually just a factory overclocked 290X. Smart shoppers obviously won't be happy to pay AMD a premium of around $100 simply for overclocking a two year old 290X. That said the 390X does offer stellar performance, particularly at 4K resolutions and if prices drop significantly it could become a strong contender. We only have one MSI sample benchmark for the 390X so far so we will revisit this GPU when we have a better sample of all the available cards. [Jun '15GPUPro]

The new GTX 980 Ti shares the same board as the more expensive Titan-X but with various restrictions including a reduced number of CUDA cores (3072 to 2816, -8.3%). Although the 980 Ti has the same 384-bit memory bandwidth as the Titan-X it only has 6GB of GDDR5 vs. 12GB in the Titan-X. So far we only have one user benchmark from a pre-release unit of the GTX 980 Ti so the following benchmarks are provisional. Comparing the Titan-X and 980 Ti shows that the Ti only lags by around 8%, which is in line with the CUDA core counts on the two cards. On the other hand comparing the GTX 980 and GTX 980 Ti shows that the Ti is around 16% faster. We don't have reliable prices for the GTX 980 Ti yet so a precise value rating isn't possible but as a card aimed at resolutions greater than 1080p it will struggle to match the GTX 970 for the vast majority of users.
